Aliasing is thankfully becoming a less frequent problem due to improved instrument designs. Users should still be aware of it ...

Wideband signal processing and compressive sensing represent transformative approaches to the acquisition and reconstruction of signals across expansive frequency bands. Traditional methods that ...

Sub-Nyquist sampling and Finite Rate of Innovation (FRI) signal processing represent a paradigm shift in the acquisition and reconstruction of signals. Traditional sampling theories require adherence ...

When you are trying to digitize a modulated RF signal, you have several choices: you can heterodyne the signal down to a lower intermediate frequency (IF) one or even twice, then digitize; you can ...

Enabling high-speed swept-source OCT with advanced data acquisition Optical coherence tomography (OCT) has become an ...

Swept-source OCT offers performance benefits in a wide variety of applications. A critical component at the core of the ...
